PREPARATION OF ULTRA-FINE CERIUM OXIDE POWDER BY MECHANOCHEMICAL PROCESSING METHOD

摘要

The cerium oxide powder has been modified with mechanochemical processing method. The effect of modifier, reaction time, calcine temperature, and amount of additives on the particle size, density, and hardness of ultra-fine cerium oxide powder was investigated. The complex ultra-fine cerium oxide powder was prepared, whose physical state and feature were characterized. The results show that modifier and powder may interact, which improves the properties of super-fine cerium oxide.
